To all whom it may concern; Be it known that I, WILmAMJnLUsm-a citizen of the United States, residing in the city of New York, borough of Manhattan, county and. State of New ork, have invented ac'ertain new and useful Automatic Fire whichthe' following is a specifica- Alarm, of

tion. a r

- This invention relates to alarms,- having reference particularly to an automatic alarm system. r v

The invention has for an object the provi-.

sion of automatic means for notifying a sta- 7 tion (remote from the location wherein the apparatus is installed) that abnormal condi- "tions exist at such location.

A further objectof the invention being to provide means for actuating the alarm mechanism, and automatic means for returning .said mechanism to inactive condition.

From a structural standpoint, the inven tion, in its neric aspect, embodies'means, adapted un or certain "predetermined condi- .tious to operate the alarm, or give a signal,

and, in the preferred embodiment of the inventlon, the signal is automatically communicated to a central .station.

In carrying out my invent1on,.I provide a normally inactive mechanism, comprising a sound (producing device, as a phonograph,

transmission device, as a telephone,

- automatic means for coincidentally actuating the sound producing device and placing the sound transmission device in -.active condition, and means 'for autom'atically"r estoring the alarm to inactive condition.

In the preferred and more specific ,form,

. the invention embodies a chain or cable which sup orts a weight in elevated position, said ain or cable being provided with; a fusible link which becomes disrupted upon the temperature reaching the predetermined melting point of the fusible solder of the link, whereupon the weight falls and'performs twofunctions, namely: it releases a brake on a phonograph positioned in proximity to a telephone and elevates the receiver of the phone, whereby the special message on the phonograph record is automatically transmitted to the transmitter of the phone and thence to the central hone station. The

central station can then notify the fire department;

Means is preferably provided whereby, at a subsequent period, dependent on the melting of a fusible link, the solder of which melts at ahigher tem raturethah that of the first link,'the telep one receiver after detailed description taken in conjunction with the accompanying drawings.

In the accompanyin" drawings, 1 have illustrated one praetica .form of the invention, but the construction shown therein is 5 to be understood as. illustrative only, and not as defining the limits of the invention.

The drawing is-a perspective view of the complete apparatus, posi ioned within a casing, a portion of which latter is broken 0 away.

Referring. to phone, positioned, for convenience, on a shelf or bracket2, the receiver being designated 3 and the receiver support 4, the latter. being 75 associated with a ring, o'requivalentdevice 5,'f'or the purpose hereinafter described. A J

phonograph sound box is shown at 6, the

record being designated '7, the reproducer grees F. f The other end of the cable is at 'tached to the outer en of the brake or pin 10 on the phonograp'. Cable 12' extend s over guide pulleys 15 as shown, and at one point in the'cable, preferably-near its lower 6 end, is sus nded a weight 16.. A branch chain or ca le 17 extends upwardly from the main cable, thence over guide pulleys 18 mounted on bracket 19, whereupon-'its'end is attached to; ring 5 on receiver support. 4. This branch cable is provided with a fusible link 20, the temperature of disruption of which is somewhat higher than that of fusible links 14; e. g., it might be 160 F. The reason for the difference in temperature will be explained later. 7

The apparatus described is preferably housed in a casing 21, in the interest of attractiveness and rotection, although it will be understood t at said casing does not the drawings, lisa telev a predetermined temperature, e. g.," de 2 necessarily functionwith the fire'alarm ap- .paratus. The record 7 may be made of steel to render it fire-proof, or,-if an ordinary record is employed, it may be protected by a fire-proof metal casing, not shown.

From the foregoing description, the o erarupt, will cause the weight 16 to drop, thereby exerting a downward pull on that end of the main cable 12 which is attached to the brake 10 of the phonograph, thereb leasing the brake and. setting the p onograph in operation. The downward movement of weight 16 simultaneously exerts a downward pull on branch cable 17, thereby elevating the receiver support 4 through the medium of rings 5, and thus putting the phonograph in communication with the telephone through the horn or pipe. 11. The result is that the notation on the phonograph record 7 is communicated to the local telephone 1, through the horn 11', and thereupon transmitted to the central station. The record 7 will be provided with an a proximate notation to indicate that a re has broken out in the location where the ap aratus is installed, such as A fire has broken out in room 1009, 277 Broadway.

I This notation may be, duplicated on the record, so as to cause a repetition thereof as often as desired. In the meantime, as the temperature ,rises, the fusible link 20 in branch cable 17 becomes disrupted, thereby freeing the branch cable from the action of weight 16, with the result that the. upward pull on receiver support 4 ceases, whereupon the receiver drops by gravity, thereby shutting off phono communication with the central station. In the meantime, however, central station is presumed to have notified the fire department or, as will beobvious, if

special wiring is provided, a particular fire department might be notified directly.

It will be.obvious that slight changes may be made in the apparatus described, such as,

the substitution .of equivalents, or that part of the apparatus specified might be used either alone or in other relations, without necessarily employing them all in conjunction, without departing from the spirit or substance of the invention, the scope of which is commensurate with the appended claims.

What I claim as new and desire to coverfusiblelink positioned in said cable, whereby when the link is disru ted b heat the weightfalls, a phonograpl i, a te ephone in proximity thereto, means whereby the falling of the weight releases a brake on the phonograph, thereby ermitting it to operate and, simultaneous]? lifts the receiver of the phone. whereby the message of the phonograph is sent into the phone and means for subsequently restoring the receiver to hung-up position. v
